The Boxers had a lot of the latest rifles and artillery. It involves anti-modern forces (with modern weapons) and pro modern forces (also with modern weapons) and troops from various outside nations. The Boxer Rebellion is in gameplay terms similar to FotS. I think that the next Total War game will also be set in this era because of this and one particular setting stands out to me as a possibility. I doubt that CA would go to the trouble of making all these major gameplay changes and new models just for an expansion. In the FotS DLC, there will be gatling guns, coastal artillery, campaign map bombardment and battlemap offshore bombardment abilities and more modern weapons and warships.
